My pool is about 7ft from fence, and i need to dig a trench about 70ft long. About 10ft (will bring pvc at 45 degree angle to fence and out 45 deg to other side of pool) will run along fence and the land abruptly slopes by fenced area to keep the dirt off the fence.
The slope starts about a foot away from fence, right where I would like to start the trench. Im debating hand digging, but I would like to get the smaller 18inch deep trencher .. so im wondering if i am able to run a board to help keep trencher straight, what would be reference to measure for depth? The higher side or low side of soil?
I ask mostly because if i needed to go deeper a ditch witchis much too big, and I am using pvc conduit so I will need to dig the rest otherwise. I figure with the 18inch trencher i can use my 15lb digging bar to smash down the extra inch so 18 inches measures from top of conduit. But now im wondering how the slope will play into this.

The depth of the trench is measured from the final grade above the conduit. So It would be measured from a point right above the conduit, which would be about the average of the slope. However, most inspectors aren't going to ding you for an inch or two. In fact, most inspectors don't even measure, unless it looks too shallow.
